ROVlNG-GUIDE TRAVERSE-MOTION.

SPECIFICATION forming part of Letters Patent No. 770,440, datedSeptember 20, 1904,

Application filed February 9, 1904. Serial No. 192,759. (No model.)

To a, whom it may concern:

Be it known that I, LOGAN OWEN, a citizen of the United States, residingat Macon, in the State of Georgia, have invented certain new and usefulImprovements in Roving-Guide Traverse-Motions, of which the following isa full, clear, and exact description, reference being had 'to theaccompanying drawings, forming a part of this specification.

In my prior patent, No. 7 27 ,191, dated May 5, 1903, I have described adevice wherein the roving-guide is driven from the builder-mo tion byconnections between the guide and lifting rail.

It is well known that in the various forms of slubbers, speeders,fly-frames, and the like the lift-shaft for the builder-motion is givena varying rotating motion first in one and then in the other direction.For instance, assuming that the maximum rotative movement is onerevolution, said shaft then revolves in the opposite direction to verynear the startingpoint or to a point approximately one-half the diameterof the roving from the starting-.

point. Then it moves in the first direction to its maximum travel lessone-half the diameter of the roving, then back again to thestartingpoint less one-half the diameter of the roving, continuing todecrease the travel at each upward and downward movement of thebuildermotion until the minimum travel is reached, at which point thebobbin is full, forming the bevel on each end of the bobbin. When thisprocess is completed, the builder-motion has again reached a point togive its maximum travel, the filled bobbin is doifed and an empty bobbinput in its place, and the process is repeated. In the present embodimentof my invention I have taken advantage of this varying rotative motionof the lift-shaft to impart to the roving-guide the varying motiondesired to prevent undue wearing of the drawing-rolls and in the presentinstance have provided the roving-rod with two guide eyes closetogether, which lead between the same pair of drawingrolls, wherebyunder the varying movement of the roving-rod the paths of movement ofthe rovings will be caused to overlap or cross each other near thecenter of the rolls.

In the drawings, Figure 1 is an elevation of a detached portion of aspinning-frame embodying one form of my present invention, some of theparts being omitted to more clearly illustrate the mechanicalconstruction,

which more particularly pertains to the inventhen in the other directionto properly lay the yarn upon the bottom, as will be understood. Mountedupon the frame A are the usual drawing-rolls C, back of which isarranged the roving guide-rod D, movable longitudinally in suitablebearings, as d. The roving guiderod D is preferably provided with twoguideeyes d and d for each of the rolls O, whereby the eyes d and clguide a plurality of rovings between upper and lower drawing-rolls.Secured to the lift-shaft B is a beveled pinion B, which engages asegmental rack E, mounted to oscillate on a pivot E, carried by abracket E The part' carrying the segmental rack E may for convenience ofidentification be termed the rack-plate F, the end thereof opposite therack E being connected to a rod f at l f the opposite end of said rod fhaving a pivotal connection at f 2 with a lever f The lever f 3 ismounted on a pivot pin or stud f of any usual form, carried by suitable.bracket-arms f depending from the main frame A. that the lever-arm f 3may be adjusted, the ends of the bracket-arms f are slotted at f.Connected to the end of the lever-arm f opposite the pivotal connectionf is a rod g, the upper end of which at g connects with one arm, 9 of abell-crank lever, the other In order arm of which, 9 is provided with aslot g engaging the pin g on the roving guide-rod. The bell-crank leverhaving the arms g and g is pivotally mounted upon a stand 9 which has aslot g for adjustment of the bell-crank lever, as will be obvious.

From the construction described it will be noted thatas the lift-shaft Bis rotated first in one and then in the other direction it will throughthe gearing connection of the pinion B and rack E impart to the rovingguide-rod D a reciprocating movement, and the length of eachreciprocation of the roving guide-rod will depend upon the degree ofmovement given to the lift-shaft B. The lift-shaft B has imparted to itby the usual builder mechanism varying degrees of rotation first in oneand then the other direction, the maximum of such rotative movement,however, usually not exceeding one complete rotation of the lift-shaft,from which it will be obvious that the transverse movement of the rovingguiderod D will also vary as the movements imparted to the shaft arevaried. The movement thus imparted to the roving guide-rod D will causethe paths of the rovings to be carried past the center of thedrawing-rolls at each reciprocation, so as to equalize the wear on eachside of the center thereof.

It will be obvious, of course, that various adjustments may be made inthe connections between the lift-shaft B and the'roving guiderod D, soas to change the path or degree of reciprocation given to the rovingguide-rod as desired. Changes may also be made in the construction andthe gearing connection between the lift-shaft and the roving guide-rod;but the essential characteristic of this feature of invention is inproviding gearing connection of some character directly between thelift-shaft and the roving-rod to give reciprocal movement to the latter.

In Fig. 2 is illustrated a modified form of the device where thelift-shaft B is provided with a gear B secured thereon, said gear Bmeshing with the rack B and said rack having suitable guide-lugs Z) fordirecting its upward and downward movement under the reverse rotativeaction of the lift-shaft. Connected to one end of the rack B isa leverb, pivoted at b in the slotted bearing 6 of the bracket-arms b, the endof said, lever Z2 being connected at b with a rod 6, which at itsopposite end engages a bell-crank lever g g similar to that alreadydescribed. From this construction it will appear that as the liftshaftis rotated first in one and then in the opposite direction it will movethe'rack B up and down and through the connections described give thedesired reciprocating movement of varying extent to the roving guiderodD.

In Fig. 3 still another modified form of invention is shown wherein thelift-shaft B is provided with a worm H, secured thereto, the said wormengaging the end of the lever H,

pivoted at h to the bracket-arms h, the upper end of said lever H havinga slot 7L directly engaging a stud h secured to the roving guide-rod D,whereby reciprocating movement is imparted to the roving guide-roddirect from the lift-shaft B as the same is rotated first in one andthen in the other direction.

It will be noted that the rovingguide-rod in each of the forms ofinvention shown is given its traverse-motion through gearing connectionsfrom the lift-shaft and that the roving guide-rod contains a pluralityof guideeyes for each pair of drawing-rolls, the reciprocal movement ofthe roving guide-rod being such that the paths of movement of therovings will by reciprocation of said rod be caused to pass the centerpoint of each pair of drawing-rolls, and while I have shown theparticular embodiment of my invention in the forms hereinbeforedescribed I wish it to be understood that I do not regard my inventionas limited to the details of structure disclosed, which may be changedwithin wide limits, the essentials of the invention being gearingconnection between the roving-rod and the liftshaft for reciprocatingthe former and carrying the paths of the rovings to opposite sides ofthe center of the drawing-rolls.

The lever and rod connections between the roving guide-rod and thegearingactuated by the lift-shaft B may be generally designated as anactuator and the form of such lever and rod connection or actuator mayvary within wide limits, as will be obvious, without departing from thespirit of my invention.

Having-thus described my invention, what I claim, and desire to secureby Letters Patent, is-

1. A roving-guide traverse-motion comprising a roving guide-rod throughwhich the material is delivered to the drawing-rolls, an actuatortherefor, a lift-shaft and means connecting the lift-shaft and theactuator.
